Festo
The Festo 1635980 is a directly controlled piston regulator featuring a 3 mm nominal width for both pressurization and exhaust, utilizing a soft sealing principle and a mechanical spring reset method. This 3-way proportional pressure control valve closed offers a pressure regulation range of 0.4 bar to 40 bar (0.04 MPa to 4 MPa) within an operating pressure of up to 50 bar (5 MPa), and incorporates an LED display along with reverse polarity protection for all electrical connections. Equipped for electrical actuation with a maximum cable length of 30 meters, the unit features a safety position that drops outlet pressure to 0 bar if the power supply cable breaks, and can be mounted in any position though preferably upright.
